Feed additive for improving summer laying hen heat stress

Abstract

The invention belongs to the technical field of chicken culture, and particularly relates to a feed additive for improving the summer laying hen heat stress. The feed additive is prepared from the following raw materials: acacia leaf extracts, fermented radix ampelopsis powder, complex vitamin, selfheal spike extracts, betulin, pteridine, yam powder, blackfungus powder, pear pulp and flos gardeniae juice. The feed additive is green and pure natural; the feed nutrition supply is effectively reinforced; the body heat radiation is promoted, so that the breathing speed is in the normal state; the palatability of the feed is improved; the intake is promoted; the secretion of thyroid hormone is promoted; the gastrointestinal peristalsis is promoted; the chime intestine passing time is shortened; the fast digestion is realized; the adsorption and the utilization of nutrition ingredients can be promoted; the heat stress resistant capability and the disease resistant capability of the body can be enhanced. The feed additive has the advantages that the heat stress occurrence rate of hens can be reduced to 0 to 1 percent; the average egg yield in 60 days can reach 46.9 to 47.5 eggs / hen; the average egg weight reaches 64.51 to 64.83g / egg.

Description

technical field [0001] The invention belongs to the technical field of chicken breeding, in particular to a feed additive for improving heat stress of laying hens in summer. Background technique [0002] With the development of breeding technology, large-scale breeding of laying hens has become very common in my country. During the breeding process of laying hens, due to the high breeding density, the temperature in the chicken house tends to be high, especially in summer when the temperature is high. Sensitive to temperature, prone to discomfort in a high temperature environment, in a state of heat stress, directly affects the production performance of laying hens, the feed consumption of laying hens is reduced, the feed utilization rate is low, and the immunity of laying hens is reduced, and other diseases are prone to occur. In addition to strengthening temperature control, measures to alleviate heat stress in laying hens are mainly to add anti-stress drugs to the feed. The...

[0002] With the development of breeding technology, large-scale breeding of laying hens has become very common in my country. During the breeding process of laying hens, due to the high breeding density, the temperature in the chicken house is easy to be high, especially in summer when the temperature is high. Sensitive to temperature, prone to discomfort in a high temperature environment, in a state of heat stress, directly affects the production performance of laying hens, the feed intake of laying hens is reduced, the feed utilization rate is low, and the immunity of laying hens is reduced, and other diseases are prone to occur. In addition to strengthening temperature control, measures to alleviate heat stress in laying hens are mainly adding anti-stress drugs to the feed. There are drug residues, strengthening nutrient supply, and avoiding drug abuse are reasonable ways to solve the above problems.
